To 'all whom it may concera Be 31 known that I',ILHELM'SONNBERG, a sub ect of the King of Prussia, residing at certain. nw' and .usefifl improvements in: Cages-for; -Ball-Bearingsj,;ofgwhichthe-folio hepresent'inventi I I I I II and undivided cage; 1n which the balls are held 'hn-fpockets closed by bending over lugs or the like, and allow as far as possible fi'eeplayin the'rotai'yjdi rection, but provide a firm bearingat the axes of rotation: or near the same. This cage may consist of a casting of brass,

the lugs, 'which form the wall or walls of the ockets by being bent over, are rigidly ormed with the cage by casting or otherwise, or in any other suitable manner. The cage thus constructed has. the advantage of the utmost simplicity and" durability,

and consequently there are no parts to be held together by special connecting pieces so that there can be no accidental loosening of the parts of the cage, thus altogether exconsists of a partitioned ring-like cast pressed or stamped part n, with lugs b' which are cast on or bent out from the ring itself, such lugs 12 beingprovided on each sideofeach recess a for the balls. After theballs have been inserted between the lugs b which form together withthe Walls v of the recesses a pockets for the balls, the

lugs are bent around inward or toward one another whereby a completed. cage obtained as may be seen in Figs. 3 and 4.

The cage 'thus forms a single rigid undivided part which each of the balls is held in a],

their axes of rotation or near the same but ljare'freeto rotate in either direction.

separatepocket, whose, Walls are formed by, ,the recess a andby the lugs 'b. Preferably, theFballS are so'heldthat they rest only on It must be'expressly observed, that the partitioned rigid cast or t. I

pressed ring but e construction, in which lugs may be'rivieted or otherwise suitably -attached to the the lugs are formed in one piece with the cage, is to be preferred, that is to say, in which they are cast together with the cage, and in which the material is so chosen that it permits a subsequent bending over of the In s afterthe insertion of the ball.
